Examples of javax.persistence.NonUniqueResultException

javax.persistence.NonUniqueResultException
Thrown by the persistence provider when getSingleResult() is executed on a query and there is more than one result from the query. This exception will not cause the current transaction, if one is active, to be marked for roll back. @author Gavin King

        List result = getResultList();
        if (result == null || result.isEmpty())
                throw new NoResultException(_loc.get("no-result", getQueryString())
                        .getMessage());
        if (result.size() > 1)
                throw new NonUniqueResultException(_loc.get("non-unique-result",
                        getQueryString(), result.size()).getMessage());
        try {

        } catch (Exception e) {
                throw new NoResultException(_loc.get("no-result", getQueryString())
